IMPROVEMENT IN REGULATORS FOR TYPE-SETTING MACHINES.

I Specification forming part of Letters Patent No. 150,234, dated April28, 1874; application filed December 12, 1873.

To all whom it may concern Be it known that I, J oHN M. FARNHAM, ofHartford, in the county of Hartford and State of Connecticut, haveinvented certain new and useful Improvements in Regulators for Type-Setting Machines 5 and I do hereby declare that the following is a full,clear, and exact description thereof, whereby a person skilled in theart can make and use the same, reference being had to the accompanyingdrawing, and to the letters of reference marked thereon.

Like letters in the figures indicate the saine parts.

My invention consists in certain improvements upon the regulatingmechanism described and shown in the Letters Patent of the United Statesissued to me May 21, 1872, for improvement in type-settin g machines.

The said improvements consist in arranging a band around the wheels ofthe regulator to press against the types as they descend; also, inproviding springs for the axes of the wheels, so that they have anelastic yielding motion as types of different thicknesses pass when intheir descent through the type-channel, and are pressed iirmly againstthe types to control their motion. It also consists in making the lowerwheel or wheels of the series of regulatin g-wheels, revolve morerapidly than those above, for the purpose hereinafter stated.

In the accompanying drawing, Figure l shows a front view of myimprovement. Fig. 2 is a side view of the same. Fig. 3 is a sectionthrough the middle of the regulatingwheels.

u. is a part of the frame of the machine. b and c are two side plates,between which the regulating-wheels revolve, and which support the partsof the regulating mechanism. d is the pulley which gives motion to theregulator. e is a pulley upon the same shaft which drives the pulley gby means of the belt f. 7L is one of the regulating-wheels on the sameshaft as the pulley g, and moved by it. t' is another regulating-wheel,around which and the wheel 7L passes the belt j, which presses againstthe descending types. The belt j has leaves or projections, (shown inthe drawing,) to preserve the proper pressure and friction against thetype; but my invention is not confined to this particular surface; anysurface of rubber, leather,.or other material that will hold the type,may be used. k and l are two pulleys or rollers, for pressing the band jagainst the type. They may be of the saine size or smaller than thewheels h and t'. m is a pulley iixed upon the same shaft as the wheel i,and turns with it. It drives the smaller pulley o by means of the belta. p is a regulating-wheel fixed to the same shaft as o, and moved byit. It has, as shown in the drawings, the elastic projecting radial armsq, which press upon the type to guide its descent and regulate itsmotion. The periphery of this wheel moves with a greater velocity thanthe surface of the band j, so that the type under it is drawn away fromthose above it, as shown in Fig. 3. The surface of this wheel may be ofany form or material that will hold and guide the type, and notnecessarily composed of the elastic arms g. r is the type-channel,through which the types descend to the regulating mechanism.

s s s s, Src., are springs acting upon the axes of the wheels h t' 7c l,to-keep them pressed up against the line of descending type. t t t aretypes passing' through the regulator. t is a type passing under the morerapidly moving' wheel p, and is separated thereby from those above it7leaving a space or opening between it and the next, as shown in thedrawing. Below the regulating mechanism there is a valve or stop, whichis connected with the type-setting mechanism below it, and with theregulating mechanism above it, so that they all move conjointly torelease and set the type at regular intervals of time.

Vhen the valve stops the type-chann el, the types above move downward,and form a solid column resting upon it. Vhen it is withdrawn, thecolumn moves downward under the influence of the regulator. The lowertype, bein g passed rapidly down by the quicker-moving wheel p, dropsinto the setting mechanism, giving the valve an opportunity to enter thechannel and arrest the column before its action is impeded by thearrival of the next type.

My improved regulating mechanism is applicable to any machines whichbring the types into one channel to be set by a self-acting settingmechanism.

The types, as they are let ont of their proper receptacles above by theloperation, are supposed to fall consecutively into the main channel v'.If dropped farther than the regulator passes them, they are detained bythe types below. The revolution of the regulator-wheels, or of the beltsurrounding` them, carries -thel types downward, unless stopped by thevalve, in which case the Wheels revolve against the types until they arereleased by the withdrawal of the valve, when they move downward, asbefore described.

By means of this regulating,` mechanism, lthe types are delivered one byone, at regular inl tervals, to be set in line, no matter how fast, orirregularly they may drop into the main channel above by the action ofthe operator, who releases the types `in their proper order 1 from theirreceptacles.

ing dierent velocities, so as to separate the lower type in thedescending column, substantially as and for the purpose hereindescribed.
